I was arrested for small amount of marijuana in December due to driving a female home from community college nad being pulled over for window tints. She left the substance in the vehicle on the floor when asked to search the car since it smelled slightly due to the substance. I was accepted into ARD which means after 6 months probation it will be dropped completely due to the female denying the substance to be hers and I was operating the vehicle, even though it was on her side of the vehicle. I passed my series 6 in February, and 63 in March, and my licenses have been active. I take my series 65 tomorrow and am wondering if this is will be a cause for denial or if I need to disclose it to be an IAR.
